Google sets minimums to keep out advertisers that are trying to simply arbitrage visitors that they can get for $0.01. They may set $0.10 because they know the quality will be good enough at that bid to only attract people that have a legitimate use for the keyword. We have some advertisers that do in fact pay $0.05 but that is the exception and not the rule. Rob Lenderman Co-Founder BoostCTR It is not accurate to assume $0.01.

In your example were the positions of the two ads the same? Google uses a QS for each ad/keyword combo and part of that is from historical performance as well as defaults from other areas of the account. If one ad was new he could have been suffering from using defaults more than his own performance. Usually this shows up in the position of the ad which can lead to much lower CTR's. This is something that actually hurts our ability to win because we use the same bid but have a lower position which leads to more losses. We are working on looking at multipel variables beyond just one metric as well as trying to correct for things that can skew measurements. Rob Lenderman Co-Founder BoostCTR Daniel,

You are correct... it takes some time and clicks for the margin of error to even out. “One of my tests between two identical ads has 70 total clicks and cumulative CTR difference of 46.29%”

Wow, that is quite a difference. You are correct… it takes some time and clicks for the margin of error to even out.

Some of the statistical significance tests (chi-squared, t-test) have some limitations. What I've begun doing is making identical duplicate ads in many of my groups, running both at the same time, and tracking how many total clicks it takes for the cumulative difference in CTR between the two identical ads to get close to 0%. The difference between two identical ads CTR at any given # of total clicks would be the margin of error. It took my most popular ad about 250 total clicks between the two identical variations before the cumulative CTR difference fell below and stayed below 10%. Using too small a sample size can lead to terrible conclusions. One of my tests between two identical ads has 70 total clicks and cumulative CTR difference of 46.29% I appreciate it.

It factors in both number of actions (clicks) as well as the difference in CTR between the two ads. The less difference there is, the more clicks are needed. The greater the difference, the fewer the clicks are needed. So each contest is a bit different. In spite of the algorithm, all contests where the Challenger is winning run for a minimum of two weeks. Contests where the Challenger is losing are killed after four days. Ryan Hi Daniel,
